this is a very good product. I tested with my oscilloscope and the wave generated is basically a perfect Sinusoidal wave. this product works very well. keep in mind this has a 30 amperes out but is only 110 Vac. this model doesn’t have a 220 Vac output.

The first thing I noticed when I unboxed this device is how sleek and modern it looks. Many of the solar generators that are out there today are just plain boxy and very utilitarian. Visually comparing this device to some of the others on the market is like comparing a Porsche 911 to a box truck. I know, kind of an outlandish comparison, but you get my drift. This device has some excellent features that are worth noting. One is the slide switch on the back where you can select "fast" or "adjust". What this hardware switch does is allow you to leave it always on "Fast Charge" where it will charge at the maximum available input, or allow you to make it adjustable via the EcoFlow app. For example, out of the box this device was set to fast and when I plugged it in it automatically started charging at 1600 watts. Since I have it plugged into a residential quality power strip/surge protector, I decided to move the switch to adjust and via the EF app, I changed it to 800 watts. The app gives you an approximate amount of time it will take to fully charge. It was incredibly easy to install the application and add this device. I did not even have to tell it to search for the device, it popped up automatically and asked if I wanted to add it to the app. Since I already have another EF device, the app knew the settings for my WiFi connection so it gives you a one button connection option. I pushed one button and boom, it immediately started adding the necessary information to connect via WiFi. I have several screen shots of the app as it showed me various options it has, such as port priority, AC overload protection, and Storm Guard. I will start with Storm Guard because I think it is a really cool option! Storm Guard monitors the weather in my area, and when it detects a severe weather situation, it will (depending upon settings) immediately charge the battery to 100% and go into backup or standby mode in case of power loss. If it is not connected to the grid, it will send you a notification on the app and recommend that you connect it to AC power to charge it. This is a really cool option that really works. We have had several vary bad storms in our area, including some tornados and huge hail that damaged cars and homes. EcoFlow notified me in advance about the storm using this very handy option and I was able to fully charge my device. The app allows you to remotely control the device so you can place it where it makes the most sense to use it but still control it from the comfort of your favorite recliner. You can power on and off various AC ports, which include some of he 115V AC plugs or the incredible 30AMP RV plug on the front. This device has the capability to plug directly into a generator inlet box, although you would have to watch closely on how much you are trying to power as it is not as robust as some of the larger capacity EcoFlow devices. One cool feature is the ability to prioritize which AC port is powered. So for example, say there is a power outage and you use this device as a UPS (Yes, it does have awesome functionality with a switchover time of a few milliseconds!) for your computer and for the kids TV. You are ready to stop using the computer and you still want the kids to be able to watch the television. Turn off the power port that the PC is using but leave the one with the TV turned on. In the past with other devices, it was all or nothing. If you wanted to limit what it was powering, you had to physically unplug something. Overall, setup was a breeze and this will do nicely as a UPS for my son's room. I intend to use it exactly like the setup I described earlier. One port powering the PC, and the other port powering the television and streaming devices. This will help provide the support his gaming computer needs but then allow the grandkids to watch television. Unfortunately, in my area we are prone to power outages if there is any kind of significant storm at all. Now, I have the peace of mind to know that we have a good device that is going to take care of our emergency power needs for my son and my grand kids. Worth absolutely every penny!!

Simple solution for silent power and solar. Running my camp trailer off of this Delta 3 Ultra Plus... have it stored under my dinette bench and running my 30a trailer plug directly to it. This allows all the functions of my trailer when traveling and without hook ups or running my generator. Having this unit on board has allowed me to swap out my inefficient small propane fridge for a residential 120v mini fridge and run power to it constantly even when traveling. Using basic functions like fridge, Led lights, 12v diesel heater and some TV usage, and brew a few coffee pods, I've gone a full weekend using only about 75% of the charge. I can fire up my generator, set the charge limit to 600-800w to keep the generator idled down low and quiet, top unit off in an hour or two and be good to go again for another day or two.... I used to run my generator nonstop for very small electrical needs, this has eliminated the need for that. I also purchased a 400w Renogy solar blanket and have ran a solar cable to the electrical port on the side of the trailer. Looking forward to trying this out as summer approaches to keep this topped off and possibly eliminate the need for my gas generator altogether.... I know I could have went with a hard mounted solar set up with house batteries, but for the cost and plug and play convenience, as well as the option to pull this out and use it in the house or elsewhere, this just made more sense for me.

I recently purchased this unit to replace a 20 year old gas generator after realizing what a pain it was to deal with the old unit outside in a snow storm! I have not had the opportunity to use the Ecoflow too much but, it certainly seems to offer what I needed for a back up to power outages. It is heavy yet, easily portable with an extendable handle and built in wheels. Fits in a closet. Since it was delivered on a very cold day the unit had to get to room temp before it could be charged. It is recommended that the unit be partially discharged occasionally to maintain the battery. I have powered numerous small appliances at a time and the reserve power hardly diminishes. I'll update as it is used more often.
